Gangster Squad Review | Leviathyn

Leviathyn | Los Angeles, 1949. Crime has a new boss in the form of Mickey Cohen, played by Sean Penn, though he seems to be doing a Robert DeNiro impression for much of the time. Cohen is not stoppable by the regular police because he kills everyone that’s dumb enough to decide to testify against him, so the police chief decides that he needs a force that’s outside the law to take him down. And that force’s name is the Gangster Squad, made up of war veterans, at least one pulp hero, and a couple of younger guys to act as sidekicks.
